Their splitter (take this with a grain of salt because they've only thrown 15 of them in 2024) is thrown extremely hard, has dives down out of the zone, generates an extremely high number of swings & misses compared to other pitchers' splitters, has surprising cut action and is an extreme flyball pitch compared to other pitchers' splitters. Their slider (take this with a grain of salt because they've only thrown 14 of them in 2024) results in more flyballs compared to other pitchers' sliders, has short glove-side cut, is much harder than usual and has less than expected depth. Their sinker (take this with a grain of salt because they've only thrown 13 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has little sinking action compared to a true sinker.
